The Snugga Wubba by KONG is a great interaction and snuggle toy.
It isn't 100% stuffing free, but there is very little in there!
They are made of two balls, covered in snuggly fleece material.
The long ribbons make it ideal for tug-of-war and fetch.
The irregular shape makes is difficult to predict where it will land when thrown, which keeps your dog on their toes during games of fetch.
The best thing about it for us humans though is that it contains no squeak...so a little peace and quiet for your ears!!
